IMPROVEMENT IN escom-MACHINES.

Specification forming part of Letters Patent No. l 74,038, dated February 2:2, 1876; application filed December 24, 1875.

To all whom it may concern Be itknown that we, ALPHoNso WALRATH and EDWARD D. BRoNsoN, of Amsterdam, in the county of Montgomery and State of New York, have invented a new and valuable Improvement in Broom-Machines; and we do hereby declare that the f'ollowing is a full, clear,

and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this speciication, and to the letters and figures of reference ma-.rked thereon.

Figure l of the drawings is a representation of a plan view of our broom-machine, and Fig. 2 is a detail view of the same. Fig. 8 is an end view thereof; and Figs. 4, 5, 6, 7, and 8 are detail views. y

This invention has relation to machinery which is designed for the manufacture of brooms; and the nature ot' our invention consists, irst, in the novel form of the holder for facilitating the application of the layers ot' broom-corn upon the handle during the winding operation, as will be hereinafter explained; second, in a circular rotary cutter for trimming the shoulders of the brooms, which cutter is applied on a shaft which can be vibrated by means of-a hand-lever, as will be hereinafter explained.

In the annexed drawings, A designates the frame of the improved machine, and B a hollow mandrel, which latter is sustained in a horizontal position at the front part ofthe frame. This hollow mandrel receives rotary motion from a driving-shaft, G, by means ot' pulleys a b and a belt, c. D designates a circular conical slide, which is appliedonthe mandrel B and formed with an annular groove, d, which is embraced by the bit'urcated end of a lever, E, pivoted to one side of the frame A so that it can be acted on by a curved handlever, F, which passes through a long staple,

' e. To one end of the hollow mandrel B three clamping-levers, B', are pivoted, having selfadjusting jaws j' on the ends of their shortest arms, which, when the slide D is forced against their longest arms, will rmly gripe and hold a broom-handle, g, in a proper position for fastening the broom-corn to it. G designates a device which is secured to a projecting bar of frame A, and which is used f'or holding the broom-corn while it is being fastened to the handle g. This device is formed of wire bent somewhat in the form of the letter C, with one limb extending above the other for the purpose of catching and gathering in the broomcorn layers as they are successively applied on the handle. The wrapping-wire is taken from a spool, not shown in the drawings, and passed between two disks, h h', having beveled peripheries. The disk It is constructed with a hub, h2, which is free to turn on a shaft, H, on which hub the disk h1 is applied; also a rubber washer, t, and a nut,j. By adjusting the nut j any degree of tension can be applied to the wire. This is a very convenient device for holding the wire when broken off after the operation of winding a broom. J designates a shaft, which isjournaled in a boX,-k, and a vibrating lever, K, and rotated by means of a belt, Z, passed around pulleys Z l. One end of this shaft J has a circular' cutter, m, secured to it, which may present a knife-edge or a serrated edge. After the broom-corn has been wound upon the handle, what is technically termed the shoulder is formed by bringing the cutter m in contact with the wrapped ends of the stalks, which cutter will neatly trim them; Any desired angle or bevel can be given to the shoulders by raising or depressing the journal-box la.

What we claim as new, and desire to secure by Letters Patent, is-

1. In a broom-machine, the C-shaped holder G, formed ot' wire, with one limb extending above the other for the purpose of catching and gathering in the broom-corn, in combination with a broom handle holder, substantially as described.

2. The rotary cutter-shaft J, having its outer.

end bearing in,a block journaled in the frame of the machine, and its inner bearing in a perforation in the vibrating lever K, in combination with the mandrel B, having clampinglevers B', substantially as described and for the purpose set forth.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.

ALPHONSO WALRATH.

EDWARD D. BRONSON.
